✔✔In the case of a drawing callout for a hole feature, you may see a 2X or a 4X. The
number and X simply note: - ✔✔How many times on the drawing that identical feature
exists

✔✔A "tolerance" on a drawing tells the machinist the amount and the direction that a
feature can deviate from a dimension on a drawing. True or False - ✔✔True

✔✔Each dimension on a drawing will have a varying number of digits to the right of the
decimal point. Generally speaking, the number of digits to the right of the decimal point
tells the machinist how critical that dimension is. True or False - ✔✔True

✔✔What does the term "one-thou" stand for? - ✔✔1/1000 of an inch or .001

✔✔On a standard scale (ruler, yardstick) or inspection tool, each line is also called a: -
✔✔Graduation

✔✔When a drawing of a part is the same size as the actual part, the scale is: - ✔✔1:1

✔✔When using a caliper, it is important to wipe clean the measuring faces prior to use.
True or False - ✔✔True

✔✔One of the most versatile pieces of inspection equipment to a machinist is: - ✔✔A
caliper

✔✔When using calipers to measure an outside diameter, you should remember to: -
✔✔Not push too hard, and keep the part as deep in the jaws as possible

✔✔When using the tail of a caliper to measure the depth of a feature, it is important to
watch out for corner radiuses that can throw off your measurement. True or False -
✔✔True

✔✔Calipers are great for measuring the inside diameters of holes, except when: -
✔✔The hole is smaller than .157 in diameter

✔✔What is the #1 cause of mistakes when using micrometers? - ✔✔Gorilla grip and
overtightening

✔✔For inch micrometers, the main graduations on the main sleeve are: - ✔✔.100 or
.100, .200, .300 etc

, ✔✔The thousandths graduations are etched onto the "thimble" section of the
micrometer. True or False - ✔✔True

✔✔For small holes, a good inspection tool is: - ✔✔Gauge pins or Go/No Go pins

✔✔A good measuring tool to check threaded features on a part is a Thread Gauge or
Thread Plug Gauge. True or False - ✔✔True

✔✔This video outlined the minimum math skills you will need to work in a machine
shop. For additional math skills, we suggest that you: - ✔✔Use a simple Google or
YouTube search to find the necessary additional help

✔✔It is important to be able to estimate how long a job will run, based on the total
number of parts needed and how many you can run per hour or day. True or False -
✔✔True

✔✔It is important to be able to read a tape measure when you are asked to find the
correct raw material from the raw material inventory. To read the tape measure, it is
important to understand the divisions on the tape. Typically, the smallest division on a
tape measure is: - ✔✔1/16"

✔✔A steel ruler, or steel rule, found in a machine shop is also referred to as a: - ✔✔A
scale

✔✔There are two types of scales that are common when dealing with "inches" in a
machine shop. The two types are: - ✔✔A fractional scale and a decimal scale

✔✔While the tape measure and the scale most often display fractional measurements,
the machine shop world works primarily in decimals. True or False - ✔✔True

✔✔It is not important to be able to convert fractions to decimals in the machine shop
environment. True or False - ✔✔False

✔✔In the video, there was a need for a 3/8" drill. What is the decimal equivalent for
3/8"? - ✔✔.375

✔✔It is helpful to have a Fraction-Decimal Conversion Chart in the shop, as a guide.
True or False - ✔✔True

✔✔When the Metric System is in use in the machine shop, the size of the part is usually
shown in: - ✔✔
